albertosaur.gif This is a Albertan, They kinda remind me of a t-Rex. Albertasaur means''Alberta lizard,'' It is a genus of tyrannosaurus theropod dinosaur that lived in western north America during the late cretaceous period, more than 70 million years ago. The type species, A. sarcophagus, was restricted in range of modern-day Canadian province of Alberta, after which the genus is named. scientists disagree on the content of the genus, with some recognizing gergosaurus librarians as a second species. As a tyrannosaurid, Albertasaurus was a bipedal predator with tiny, two fingered hands and a massive head with dozens of large, sharp teeth. It may have been at the top of the food chain in its local ecosystem. Although relatively large for a theropod, Albertosaurus was much smaller than its more famous relative Tyrannosaurus, probably weighing less than 2 metric tons. Fossils of more than 30 individuals have been recovered, providing scientists with a more detailed knowledge of Albertosaurus anatomy that is available for most other tyrannosaurids. The discovery of 22 individuals at one site provides evidence of a pack behavior and allows studies of ontogeny and population biology which are impossible with lesser- known dinosaurs.
Is in the same family as the t-rex

Albertosaurus was smaller than the truly gigantic tyrannosaurids like Tarbosaurus and Tyrannosaurus. Typical adults measured up to 9 meters (30 ft) long, while rare individuals of great age could grow to over 10 meters (33 ft) in length. Several independent mass estimates, obtained by different methods, suggest that an adult Albertosaurus weighed between 1.3 tonnes (1.4 short tons and 1.7 tonnes (1.9 tons).

Although the small flesh-eating dinosaurs were diverse and dangerous, Cretaceous Alberta was ruled by members of the family Tyrannosauridae. All tyrannosaurs had hind legs that were long and powerful, with each hind foot having three toes ending in enormous claws. The two-fingered front limbs were small, not much larger than a mature human arm. The function of the front limbs is not known; they are too short to have passed food to the mouth.

  • Some dinosaurs hunt in packs, and some hunt alone.
  • Some dinosaurs have feathers, and some have skin.
  • Dinosaurs are not proven yet if they are warm blooded, or cold blooded.
  • The majority of paleotolagists think they are warm blooded, because of their traits.
